Aspartate carbamoyltransferase, catalytic and regulatory chains; Similar to PID:1772605 GB:AE000512 percent identity: 100.00; identified by sequence similarity; putative; In the N-terminal section; belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.

Ornithine carbamoyltransferase, anabolic; Reversibly catalyzes the transfer of the carbamoyl group from carbamoyl phosphate (CP) to the N(epsilon) atom of ornithine (ORN) to produce L-citrulline; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. OTCase family.

Dihydroorotase; Catalyzes the reversible cyclization of carbamoyl aspartate to dihydroorotate; Belongs to the metallo-dependent hydrolases superfamily. DHOase family. Class I DHOase subfamily.

Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.

Phosphoribosylformylglycinamidine synthase I; Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thought to assist i [...]

Glutamate synthase, beta subunit; Similar to PID:2244618 percent identity: 58.52; identified by sequence similarity; putative.

Glutamine synthetase; Glutamine synthetase (GS) is an unusual multitasking protein that functions as an enzyme, a transcription coregulator, and a chaperone in ammonium assimilation and in the regulation of genes involved in nitrogen metabolism. It catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia. Feedback- inhibited GlnA also interacts with and regulates the activity of the transcriptional regulator TnrA. During nitrogen limitation, TnrA is in its DNA-binding active state and turns on the transcription of genes required for nitrogen assimilation. Under [...]

Glucosamine--fructose-6-phosphate aminotransferase, isomerizing; Catalyzes the first step in hexosamine metabolism, converting fructose-6P into glucosamine-6P using glutamine as a nitrogen source.
